Thermite grenades are a type of explosive incendiary ordnance used by the UNSC. The flames from the thermite grenade can burn underwater.[1]

Thermite grenades rely on a chemical process between metal powders and oxides to create high temperatures, with no explosion. Commonly, Aluminum and Iron (III) Oxide are used in the reaction. Thermite can reach temperatures upwards of 2500 °C (4500 °F), and is often used to melt through a wide range of things extremely quickly. However, thermite is rarely used for anti-infantry roles, and is more practical to use in anti-material roles due to quickly disabling components with few ways of interfering with the reaction.

Thermite shaped charges are also used to quickly gain entrance to locked areas.
